To all whom, t may concern:

- Be it known that l, PATRICK J. COSTELLO, a citizen ofthe United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Chocolate-Dipping Maf pieces or cores of the material to be coatedmaybe successively immersed in the coating substance and successively vibrated to re-,

move the excess ofthe coating substance from the cores.

A further object of my invention is to provide a machinefor manufacturing coated confections by means of which one of aplurality of holding devices containing a number of cores to be coated is immersed in the coating substance, While at the same time another holding device containing a number ofcores which have been immersed in the coating substance is vibrated to remove the excess ot' the coating Y substance, whereby the capacity of the ma! chine is increased by sim ultaneously subjecting to the coating processithe cores contained in a plurality of holding devices.

A further object of my invention is to provide a machine of the character described from the liquid its upward movementisstopped and it is caused to vibrate longitudinally to free the candies from the excess ofthe thick liquid chocolate which adheres to them. -While one ofthe baskets is thus being shaken the other is inverted by the mechanism, its contents removed upon a tray by the operator, and a filled basket substituted for the empty one.

In the accompanying` drawings, Figure l is a perspective view of this chocolate-dipping machine looking toward one of the rear corners thereof, showing one of the baskets as just having emerged from the chocolate-tank and the other in an inverted position, the candies having been removed therefrom. Fig. 2 is a plan view of -the machine. Fig. 3 is an Yend-elevation of the machine, taken from the end shown in the foreground in Fig. l. Fig. 4 is a' transverse vertical section on dotted line 4; et of Fig. 2 looking in the direction indicated by the arrows in said last-mentioned figure. In Fig. 4 one of the baskets and one of its supporting-arms are shown in dotted lines to illustrate the position of said `basket in the liquid chocolate receptacle. Fig. 5 is a face .View of the cam G and the vibrator-cam G3, also showing the vibratorarm aud a portionol` one of the arms upon which it is pivo'tally supported. Fig. 6 is a side elevation of the vibrator-arm, showing its pivotal support, also showing the cams G 4and G8 and the parts surrounding the outer endol:` the shaft Ein section. Figs. 7, 8, and 9 are respectively a front elevation, aside elevation, and a plan View of one of the bas- Ikot-carrying arms. Fig. 10 is a face View of lhe cam that revolves the baskets about their supporting-shafts, holding said baskets at all times in their proper positions. Fig. 1l is a ,.fragmental view of oneA of the baskets for holding the candy cores, illustrating the manner in which the basket is held by the basketcarrying arms. Fig. l2 isa View similar to that of the preceding gure, showing the basket in an inverted position and with the wooden tray for receiving the dipped candy cores Asubstituted for the wire cover of the basket. Fig. 13 is a fragmental View of the stop-Wheel, the clutch, and the clutch-shaft.

Like let-ters of reference indicate corresponding parts throughout the several views.

IOO

' frame, which cam is provided with the peripheral rim A0, extending nearly around the cam, with the peripheral channel A7,and with the channel A8, extending, somewhat like av chord, across an arc of the outer circle of the cam. A rack-segment A0 and a guide-finger A10 are fixed to the cam A5. Their purpose will be explained later herein. An offset A11 is formed in the peripheral channel A7, the purpose of which offset will also be explained hereinafter.

B is a jacketed tank of semicylindrical form,its double walls providing between them a space B for receiving steam, if it is desirable to heat the liquid chocolate within the tank, or cold water to reduce the temperature of the chocolate, if the latter is too warm.

Three stirring-screws B2 of conveyer-screw form, located in the chocolate-tank and near the bottom thereof, are fixed to their rotatable supporting-shafts B5, B4, and B5, which shafts extend through suitable stuffing-boxes B0 in one end of said tank B and bear at their outer ends the three sprocket-wheels B7, B0', and B0, respectively. The shaft B3 carries the tight and the loose pulleys B10 and B11, respectively, over the lformer of which a belt is intended to be passed from an independent counter-shaft (not shown) to drive the screws B2 for stirring the chocolate within the tank B. An endless chain belt B12 passes around the two outside sprocket-wheels B7 and B0 and over the top of the sprocketwheel B0, the proper tension of said chain belt being maintained by the pivoted arm B13, carrying the idler-pulley B14 at its free end and supported by the adjustable tension-spring B15. The movement of the endless chain belt B12 about and over the sprocket-wheels B7, B0, and B0 causes the two outer screws within the tank B to rotate in the same direction and the middle screw to rotate in a contrary direction.

C is a drive-shaft rotatably mounted in suitable bearings in the upright members A' l and A2of the supporting-frame A. This shaft C carries near one of its outer ends the drivepulley C', adapted to receive a belt passing from a counter-shaftV (not shown) to communicate motion to the mechanism. The shaft C is constantly driven throughout the operation of the machine. A pulley O2 is fixed to the shaft C within the supporting-frame A, and a belt C2, passing upward from said pulley, communicates motion for driving the mechanism which Vibrates the basket of freshly-dipped chocolate in order to shake the excess ofliquid chocolate from the cores, which vibrating mechanism will be later described herein.

04 is a sprocket-wheel fixed on the shaft C, over which wheel the chain belt C5 is adapted to run. The chain belt C5 is provided with a tighten'er-arm C0, loosely 'mounted on the shaft C. This arm carries at its outer end the idler-pulley C7, adapted to engage the belt C5, and a tension-spring C8 holds said idler-pulley C7 against said belt C5.

A clutch-shaft D is journaled in suitable bearings in the lower part of the supportingframe A. lt is provided with the sprocketwheel D', loosely mounted on the shaft D, carrying one (the free) member of the clutch mechanism. D2 is a collar having a sliding engagement with the shaft D, but rotatably secured thereto and adapted to carry the other member of the clutch mechanism. This clutch mechanism may be of any suitable form.

D2-is an L-shaped lever for sliding the clutch-collar D2 lengthwise of the shaft D. This lever is pivotally mounted upon the bolt D4 on the member A of the supporting-frame A and is in yoke form at its upper end to surround the clutch-collar D2. The opposite end of the L-shapcd lever D3 extends within the supporting-frame A and rests upon the inner end of the foot-lever D5, which foot-lever is pivotally mounted at D upon one of the horizontal rods A3, its forward end projecting within convenient reach of the operators foot. It will thus be seen that when the foot-lever D5 is depressed by the foot of the operator the clutch-collar D2 throws the clutch mechanism rotatablytixed to the shaft D into frietional engagement with the constantly-rotating clutch member carried by the sprocket-wheel D', rotating the shaft D as long as said clutch-collar is held in engagement with the free member of the clutch. At the opposite end of the shaft D is fixed a sprocket-wheel D7, carrying the endless chain belt D0.

E is the main shaft, journaled in suitable bearings, one in the center of the cam A5 and the other in the upper end of the upright member A of the supporting-frame A. The shaft E carries the two arms E' and E2, rigidly tixed to said shaft within the supporting-frame A. The outer ends of the arms E and E2 are provided with the enlarged bosses E3 and E4, respectively, and within said bosses are journaled the two shafts E5. The arm E2 is provided at each side of the shaft with two outwardly-extending perforated ears E5, between which the vibrator-arms, to be later described herein, are pivotally mounted.

A stop-wheel E7 is fixed to the shaft E just outside the supporting-frame A. This stopwheel E7 is provided on its periphery, on opposite sides thereof, with the three projections E8, E0, and E10. An arm E11, having in its upper end a roller E12 for engaging the periphery of the stop-wheel E7, is mounted upon IOO IIO

the shaft E13, journaled in the member A of the supporting-frame A. This arm is held so that the roller E12 is in contact with the periphery of the stop-wheel Eri by the helical spring E11, extending between the arm E11 and a fixed portion of the supporting-frame A. The shaft E13 also carries the downwardlyextending arm E15, having the hook E16 for engaging the under side of the L-shaped lever` D3. When the foot-lever is depressed and; the L-shaped lever D5 thereby raised, the hook E15 of the arm E15 is caused by the spring E1I1 to engage and hold elevated the L-shaped lever D5, whereby the clutch mechanism is held in clutch. As long as the two members of the clutch mechanism are engaged the shaft D rotates, driving the shaft E by means of the endless chain belt D5. As soon, however, as one of the projections E5, E5, and E1O comes in contact with the roller E12 of the arm E11 said arm is moved outward against the tension of the spring E11, rocking the shaft E13 in its bearings and withdrawing the hook E1G of the arm E15 from its engagement Awith the L-shaped lever D5, permitting said lever to fall of its own weight andthe members of the clutch to be disengaged, thus automatically .stopping the rotation of the shaft E.

E17 and E1s each represent two pins set at diametrically opposite points on the side of the stop-wheel E1, and a stop-arm E19, adapted to engage said pins as the stop-Wheel rotates, preventsa backward movement of the shaft E. A spring E25 holds said stop-arm E19 in a position to be engaged by said pins E17 and E15.

Motion is imparted to the shaft E from the shaft D by means of the endless chain belt D5, passing over the sprocket-wheel D5', fixed on the shaft D, andthe sprocket-wheel E21, xed on the shaft E.

Two basket-carrying arms F, similar in their construction, are rigidly mounted upon and integral sleeve G.

each of the shafts E5, and the baskets which they are intended to support are counterbalanced by the weights F', also dxed on each of said shafts E5 and extending in the con` trary direction from the arms E. The arms E are bifurcated at their outer ends and are provided with the stop-pins Fzand the springactuated holding-jaws F5 for grasping the handles of the baskets, to be later described, the upward movement of the baskets being limited by said stop-pins and their downward displacement by the holding-jaws F5. A spring-jaw F1 is adapted to hold in place the tray for receiving the chocolates after the same have been dipped, which tray will be more fully described laterherein. A thumblever F5, pivotally mounted one on each of the arms F, is intended to withdraw the spring-jaws F1from engagement` with the tray when it is desirable to remove the latter from the machine.

G is a cam xcd to the membervA' of the supporting-frame A by means of the hood Within this hood G a pulley G2 is loosely mountedon the shaftE, and this pulley is adapted to be constantly rotated bythe crossed belt C3, which also ex-V tends over the face of the pulley C5. A waveshaped cam G5 is formed integral with the pulley G2 and is therefore constantly rotated therewith. Each of the shafts E5 at its endv tion- G5 of the sleeve G4 th ronghout the greater `portion of its length; but at its inner side an opening is left corresponding in size to the diameter of said sleeve G4. Within the annular space in said boss surrounding said sleeve G4 is provided a helical spring G7, the

tendency of which is to slide the shaft E5 endwise in its bore in an outward direction. An adjusting-nut G5, threaded upon .the sleeve G4, limits the outward movement of the shaft E5, and a milled locking-collar G5, also threaded on said sleeve, holds said adjusting-nut in any desired position. Acollar G10 is fixed to the shaft E5 within the flange of the locking-collar G9.

G11 is a vibratory arm pivotally mounted near its center upon the bolt G12 and having at its rear end an elongated opening G15, adapted to receive the pin G14, extending through the perforated ears G5 of the head portion G5 of the sleeve G4. The forward end of the arm G11 is Vprovided with a conical roller G15, adapted to be engaged by the wave face of the cam G5, also at certain portions of its revolution with the shaft E to bear against the cam G and be raised by said cam from engagement with the wave surface of the wave cam G5. high portion of the cam G occupies about two-thirds of its peripheral surface and is at the upper and the forward side of the machine and at a point beneath the shaft E, it not being desirable to vibrate the shafts E5 while the baskets are being inserted andA `diately throws the shaft in the contrary direction,as the conical roller G15 coincides with a depression in the cam G5.

H is a pinion fixed on the'inner end of each of theshaftsE5. racksegment A9, which latter is of such a length as to impart onecoinplete rotation to` said shaft' E5. Outside of the pinion H each It is adapted to engage the IOO It will be noticed that the IIC of the shafts E5 bears a hub H, also fixed to its shaft, which hub is provided with two radially-extending arms H2 and H3, bearing at their outer ends the rollers H1 and H5, respectively. The arm H2 has the upwardlyextending stud H5, adapted to be engaged by the guide-linger A10, and thereby be held in proper position at the point in its revolution about the cam when the pinion is just coming into mesh with the rack-segment A9 to insure the registration of the proper tooth of the pinion with the rst tooth in the segment.

I is a chocolate-basket having the rectangular marginal frame I and the longitudinal and the transverse cross-wires I2, formed into loop-shaped receptacles each for containing a.

single core of the chocolate drops. Outwardly-extending handles l5, adapted `to be grasped by the spring-actuated jaws F3 and be held in the outer bifurcated ends of the arms F, are secured rigidly to the rectangular frame l at opposite ends thereof.

I4 is a wire cover adapted to be secured in any convenient Inanner over the top of the basket I in order to hold the cores for the chocolate drops in position in their individual receptacles in the baskets I. I have employed the spring-hooks I5 for engaging the sides of the marginal frame I; but any suitable means may be employed for holding the cover I1 in position.

16 is a tray adapted to lie between the arms F over the basket I and be held in position by the spring-jaws F1 after the Wire cover has been removed from the basket. The wire cover I4 is removed and the tray I6 put inl place over the basket I while'the latter is in an upright position, and the tray is withdrawn after the basket has been inverted and the chocolate drops turned out upon it.

J represents openings for the admission of steam or water to the jacket of the chocolatetank B and for the escape of said .steam or water therefrom.

In the operation of this machine power is communicated by belt passing from suitable counter-shafts to the drive-pulley C' and the tight and the loose pulleys B10 and B11, respectively. Liquid chocolate is placed within the jacketed tank B, is stirred therein by the rotating screws B2, and is kept at the proper temperature by the admission of steam or cold water into the space B between the double walls of said tank. The cores or candy to be dipped are placed within the baskets I, the wire covers I1 of said baskets are secured in position, and the whole placed between the carrying-arms F, the wire handles I3 of said baskets being grasped by the spring-actuated jaws F3 of said arms. The foot-lever D5 is depressed by the operator, causing the clutchcollar D2 to throw the clutch mechanism rotatably fixed to the'shaft D into frictional engagement With the constantly-rotating clutch member carried by the sprocket-wheel D. The motion thus imparted to the shaft D is transmitted by the endless chain belt D5 to being upright.

the shaft E, causingsaid shaft to rotate and to dip the basket I into the chocolate-tank, passing it through the liquid chocolate in said tank. As the basket I emerges from the liquid in the tank B the conical roller G15 of the vibrator-arm G11 ispermitted by the conformation of the cam `G to engage `the `wave surface of the cam G2, which irregular1 surface moves said arm in one direction upon its pivot G12, thrusting the shaft E5 endwise in its bearings against the action of the helical spring G", which spring throws the shaft in the opposite direction as each depression in the wave surface of the cam G5 coincides with the conical roller G15. Inasmuch as the cam G2 rotates with a considerable velocity, the end vibration of the shaft E5 is quite rapid and suflciently'violent to shake the excess of liquid chocolate from the dipped candies, the quantity of chocolate remaining upon the cores being regulated by the duration of the vibratory movement.

The projection Es on the stopwheel E7 causes the mechanism to stop, first, when the lower basket is in the middle of the tank B; second, when it has just risen above Vthe tank, and, third, after .it has assumed a horizontal position and has been lifted a little distance above the top of the tank B. The lower basket I continues in a position tangent to the circumference of the circle described by its revolution until the roller H1 engages the offset A11 of the peripheral channel A7 in the cam A5. When this occurs, the roller H5 is at the end of the chordal channel A2, and as the first-mentioned roller H4 is retarded the second roller H5 passes upward in said channel `A8 until the basket assumes a horizontal position. The direction of the channel As changes slightly at this point, and the roller H4 clears the offset A11 in the cam A5, and the rollers proceed side by side, the relative directions of the outer channel and the chordal channel of the cam A5 being adapted to retain said basket in a horizontal position. When the supporting-arms E and E2 assume a vertical position, one of the stop projections E8 engages the roller E12 of the arm E11, pushing said arm outward against the action of the spring E14 and withdrawing the hook E1G of the arm E15 from its supporting engagement with the L-shaped lever D2, permitting that lever to fall of its own weight and the clutch mechanism to become4 disengaged,

stopping the rotation of the shaft D, and consequently that of the shaft E. The first basket is now in its uppermost position, and if a second basket has been placed between the second pair of basket-carrying arms F the last-mentioned basket is `in its lowest position in the center of the tank B, both baskets The operator at this point removes the Wire cover l4 from the top of the upper basket I and puts in its place the tray I6, starting the machinery again by depressing the foot-lever D5. The rollers H4and H5 are directed downward by the peripheral rim A6 IOO IIO

.Wheel E7 engages the roller Eon the rim El1 and ,stops the mechanism just as the basket is inverted directly over its shaft E5. rlhe operator now presses the thumb-lever H and I withdraws the tray H6 from the face of the insupporting-frame A.

verted basket, the chocolates having dropped out of the depressions in said basket onto the tray. Again depressing the footlever D5, the mechanism is started in motion, the shaft E5 continues its rotation, and the basket I is revolved to an upright position directly lbeneath said lshait E5, Where the mechanism is again stopped by the engagement of the projection E10 with the roller E12 of the arm E11 and the consequent disengagement of the clutch members. At this point the empty basket is removed from the carrying-arms F and a filled basket with a Wire cover I4 in place substituted for the empty one. The cycle of movement is again commenced, the basket- I is tilted downward, entering the tank B in an inclined position, it standing at a tangent with the circumference of the circle described by its revolution. When the basket just inserted reaches the lowest position in the tank, the mechanism again stops, the other basket having attained its highest place, where the Wire cover I4 is removed and the Wooden tray Iis putin place. The mechanism being again started, the lower basket moves upward, emerging from the liquid chocolate in an inclined position, and when reaching a point about even with the top of the tank its forward movement is checked and its vibration commenced. The opposite basket at this point -is in its inverted position and the chocolates are being removed upon the tray I6 by the operator. After again starting the mechanism the next stop of the basket is when it has again assumed a horizontal position, its vibratory movement still continuing. It stands in this position, having the excess of liquid chocolate shaken from the candies Within the basket I, until the opposite empty basket-has been removed and auother filled one put in its place.

The cam G is fixed in its relation with the Its cam-surface is of such form that the conical roller G15 is raised from engagement with the wave surface ot' the cam G3 excepting for about one-thirdof a revolution of the shaft E. The cam GfS is constantly revolved. This is also true of the drive-shaft C, the drive-pnlleyC', and the sprocketwheel D', which carries the free member of the clutch mechanism; alsoof the shafts B3, B, and B5, carrying the screws B2 forstirring theliquid chocolate in the tank B.

From the foregoing description it will be observed that I have invented a machine for manufacturing coated contentions by means of Which a plurality of holding devices each containing a large number of cores are successively immersed in the coating substance and subsequently successively vibrated, thereby giving to the machine a largecapacity or output, inasmuch as While one holding device is being immersed another hold-- ing device is subjected to a vibratory movement to remove the excess of the coating substance.

While I have described more or less precisely the details of construction, I do not Wish to be understood as limiting myself, thereto, as I contemplate changes in form, the proportion of parts, and the substitution of equivalents, as circumstances may suggest or render expedient, Without departing from the spirit of my invention.
